Ingredients
For the Peanut Butter Fudge
- 1 cup creamy peanut butter
- 1 can sweetened condensed milk, approximately 14 ounces
Optional Additions
Although the classic version uses only two ingredients, you can customize the fudge if desired.
- 1 teaspoon vanilla extract
- A small pinch of salt
- Chopped roasted peanuts
- Mini chocolate chips
- Chopped walnuts or pecans
- A light sprinkle of flaky sea salt
The optional ingredients are not necessary for the basic recipe. The peanut butter and sweetened condensed milk are enough to create a rich and creamy fudge.
Instructions
Step 1: Prepare the Pan
Line an 8-inch square baking pan with parchment paper, leaving some paper hanging over the sides. This will make it much easier to lift the chilled fudge from the pan later.
Lightly grease the parchment if desired.
Step 2: Warm the Peanut Butter
Place the peanut butter in a microwave-safe bowl.
Warm it gently in short intervals, stirring between each interval. You only want the peanut butter to become soft and easy to stir, not extremely hot.
If you prefer, you can warm the peanut butter in a saucepan over very low heat.
Step 3: Add the Sweetened Condensed Milk
Pour the sweetened condensed milk into the softened peanut butter.
Stir slowly and continuously until the two ingredients are completely combined. The mixture should become thick, glossy, and smooth.
If you are adding vanilla or a pinch of salt, stir it in at this stage.
Step 4: Transfer to the Pan
Immediately scrape the mixture into the prepared pan.
Use a spatula to spread it evenly into the corners.
Smooth the surface as much as possible.
Step 5: Chill
Place the pan in the refrigerator.
Allow the fudge to chill for at least 2 to 3 hours, or until it is firm enough to cut cleanly.
For the best texture, you can leave it refrigerated overnight.
Step 6: Cut the Fudge
Once completely chilled, lift the fudge from the pan using the parchment paper.
Place it on a cutting board and cut it into small squares.
A sharp knife will give you the cleanest cuts.
Method
The method behind this recipe is incredibly simple.
The peanut butter provides the rich nutty flavor and creamy fat content, while the sweetened condensed milk supplies sweetness and helps create the thick, smooth texture.
Gentle warming makes the peanut butter easier to combine with the condensed milk. Once mixed, refrigeration allows the fudge to firm up into a sliceable dessert.
The most important thing is to avoid overheating the ingredients. Gentle heat is enough to soften the peanut butter and create a smooth mixture.
Tips for Perfect Peanut Butter Fudge
Use creamy peanut butter for the smoothest fudge. Natural peanut butter can sometimes separate and produce a different texture, so a regular creamy peanut butter works particularly well for this recipe.
Do not overheat the mixture. The goal is simply to make the peanut butter soft enough to mix easily.
Make sure the fudge is completely chilled before cutting. If it feels too soft, return it to the refrigerator and give it more time.
For neat squares, wipe the knife clean between cuts.
If you want thicker pieces, use a smaller pan. If you prefer thinner pieces, use a slightly larger pan.
Optional Variations
Chocolate Peanut Butter Fudge
Add a handful of mini chocolate chips to the mixture before transferring it to the pan. You can also drizzle melted chocolate over the chilled fudge.
Peanut Butter and Nut Fudge
Fold in chopped roasted peanuts, pecans, or walnuts for extra crunch.
Salted Peanut Butter Fudge
Sprinkle a very small amount of flaky sea salt over the surface before chilling. The salt balances the sweetness beautifully.
Vanilla Peanut Butter Fudge
Add a teaspoon of vanilla extract to give the fudge a slightly deeper and warmer flavor.
History of Peanut Butter Fudge
Peanut butter fudge belongs to the long tradition of homemade American candies and holiday sweets. Fudge itself became especially popular in American kitchens during the late nineteenth and early twentieth centuries because it could be prepared at home using relatively simple ingredients.
Peanut butter became an especially popular ingredient in American desserts as its availability increased. Home cooks began incorporating it into cookies, cakes, candies, pies, bars, and fudge.
Over the years, countless versions of peanut butter fudge have appeared in family recipe boxes. Some require cooked sugar mixtures and candy thermometers, while simpler modern versions rely on ingredients such as sweetened condensed milk.
This two-ingredient approach represents the easiest side of that tradition: fewer ingredients, fewer steps, and a dessert that still delivers the familiar peanut butter flavor people love.
Formation and Texture
The finished fudge should be firm enough to hold its shape but soft enough to feel creamy when you bite into it.
After refrigeration, the mixture changes from a thick, soft mixture into a dense fudge-like texture.
The surface should be smooth and slightly glossy, while the inside should remain rich and creamy rather than dry or crumbly.
Small squares are ideal because peanut butter fudge is quite rich. A little piece can be surprisingly satisfying.
How to Store Peanut Butter Fudge
Keep the finished fudge in an airtight container.
Store it in the refrigerator for the best texture and freshness.
Place parchment or wax paper between layers if you are stacking the pieces.
The fudge can also be prepared ahead of time, making it especially convenient for holidays, parties, cookie exchanges, and family gatherings.
Serving Ideas
Serve the fudge chilled or allow it to sit at room temperature for a few minutes before serving.
It makes a wonderful addition to a dessert tray alongside cookies, brownies, chocolate candies, or homemade bars.
You can also package individual pieces in small candy wrappers or place them in a decorative container for a homemade edible gift.
For Peanut Butter Lovers
If you are a true peanut butter lover, this recipe is hard to resist.
The flavor is rich, creamy, sweet, and unmistakably peanut buttery. There is no cake batter to prepare, no oven required, and no complicated candy-making process.
It is the kind of recipe you can make when someone suddenly announces that guests are coming over, when you need something sweet for a family gathering, or simply when you are craving a homemade peanut butter treat.
For an extra-special peanut butter dessert, serve a square alongside vanilla ice cream and drizzle the plate with a little warm peanut butter.
